A storage stable hydrogen cell comprising an anode cap subassembly, cathode can subassembly, and a grommet is disclosed. For one embodiment the cathode in the cathode can subassembly is configured for contact with the electrolyte. The cathode is hydrogen permeable and substantially impermeable to O2, CO2 and water. In turn, the cathode can preclude the passage of O2, CO2 and water into and out of the cell, and simultaneously can facilitate the permeation of hydrogen through at least one aperture in the cell. In another embodiment, a commercially available Zn-air cell is converted into storage stable H2 cells by sealing a membrane structure around the apertures of the Zn-air cell. Such membrane precludes the passage of O2, CO2 and water into and out of cell but allows the passage of hydrogen generated in the cell through the aperture of the cell and through the membrane.

A zinc alloy anode-based electrochemical cell, which generates gases and/or energy, is disclosed. The structure of the cell is such that a zinc alloy anode material is the integral part of housing and is in contact with an alkaline electrolyte containing minor amounts of corrosion inhibitors. The electrolyte which contains no zinc powder metal, may be in direct contact with the cathode thereby simplifying cell construction by elimination of a separator material. The cell is environmentally friendly, containing no mercury or cadmium or other toxic metals and is cost effective as it eliminates expensive amalgamated zinc powder and separator material.

An anode for use in an electrochemical cell, wherein the electrochemical cell includes a metallic casing, an electrolyte, a cathode, and an anode within the metallic casing. The anode comprises at least one perforated electrochemical zinc based sheet conductively attached to the metallic casing. A process for fabricating an electrochemical cell comprises the steps of fabricating an anode having at least one perforated electrochemical zinc based sheet conductively attached to a casing, associating a cathode with the electrochemical cell, associating an insulating microporous separator between the anode and cathode, and introducing an alkaline electrolyte to the anode and cathode through the microporous separator.

Electrochemical systems and methods for producing hydrogen. Generally, the systems and methods involve providing an electrochemical cell that includes an anolyte compartment holding an anode in contact with an anolyte, wherein the anolyte includes an oxidizable substance having a higher standard oxidation potential than water. The cell further comprises a catholyte compartment holding a cathode in contact with a catholyte that includes a substance that reduces to form hydrogen. Additionally, the cell includes an alkali cation conductive membrane that separates the anolyte compartment from the catholyte compartment. As an electrical potential passes between the anode and cathode, the reducible substance reduces to form hydrogen and the oxidizable substance oxidizes to form an oxidized product.

An apparatus for cleaning and/or disinfecting a surface or object is disclosed. In one embodiment, such an apparatus includes a container that is refillable with water. A sparingly soluble solid is provided in the container and is positioned to contact the water. The sparingly soluble solid slightly dissolves in the water to form a dilute solution that acts as a cleaning and/or disinfecting solution. The sparingly soluble solid is provided in a quantity sufficient to last several refills of the container.
摘要:
A method that produces coupled radical products from biomass. The method involves obtaining a lipid or carboxylic acid material from the biomass. This material may be a carboxylic acid, an ester of a carboxylic acid, a triglyceride of a carboxylic acid, or a metal salt of a carboxylic acid, or any other fatty acid derivative. This lipid material or carboxylic acid material is converted into an alkali metal salt. The alkali metal salt is then used in an anolyte as part of an electrolytic cell. The electrolytic cell may include an alkali ion conducting membrane (such as a NaSICON membrane). When the cell is operated, the alkali metal salt of the carboxylic acid decarboxylates and forms radicals. Such radicals are then bonded to other radicals, thereby producing a coupled radical product such as a hydrocarbon. The produced hydrocarbon may be, for example, saturated, unsaturated, branched, or unbranched, depending upon the starting material.
